技術說明

一種具干擾抑制之環狀天線結構，用以對一目標及一接收器發射一無線訊號，該具干擾抑制之環狀天線結構包含一迴路天線、一電磁能隙面及一頻率選擇面，該迴路天線用以發射該無線訊號，該電磁能隙面位於該目標及該迴路天線之間，該無線訊號經由該電磁能隙面發射至該目標，且該目標反射之一反射訊號經由該電磁能隙面傳送至該迴路天線，該頻率選擇面位於該接收器及該迴路天線之間，該無線訊號經由該頻率選擇面發射至該接收器。 A loop-antenna structure with interference suppression transmits a wireless signal to a target and a receiver. The loop-antenna structure includes a loop antenna, an electromagnetic bandgap surface and a frequency selective surface. The loop antenna transmits the wireless signal to the target through the electromagnetic bandgap surface located between the loop antenna and the target, and a reflected signal reflected from the target is delivered to the loop antenna through the electromagnetic bandgap surface. The frequency selective surface located between the receiver and the loop antenna, and the wireless signal of the loop antenna is transmitted to the receiver through the frequency selective surface.
